Here is an advertisement about two-day tour between Hong Kong and Macao.

Eighth-grader Victoria Bills is talking about money with her classmates. She is worried that a company’s stock (股票) price could fall. It may be an unusual topic of conversation for a 13-year-old. But at Bills’ school in Chicago, US, you hear it all the time.
The Chicago school’s 420 students learn about economic(经济学). They also get a chance to make money. Each 1^st grade and 5^th grade, students learn the basics of economics and investing(投资).
Then in 6^th grade, they put what they’ve learned to work. Students join a junior group that manages the $20,000. The group, made up of 12 to 14 students, decides which stocks to buy.
After graduating, students pass on $20,000 to the next 1^st grade class. They keep half of the rest of the money; the other half goes toward improving the school. They can choose to put their money in a college-savings program or take the cash.
In 2007, Bills suggested that her class buy the stock of the Apple computer company. This was just before the iPhone came out. “We bought stock just at the right time,” she says. The kids bought Google stock as it reached $400 a share. It is now worth over $500. “It was a good buy,” says Myles Gate, 13. He hopes to be a banker one day.
The school’s two graduating classes of 2005 and 2006 have each earned about $10,000 in profits(利润).

Who hasn’t enjoyed eating peanuts? Did you know that although peanuts look like nuts and taste like nuts, they aren’t nuts at all? They belong to the pea family, so they are called peanuts. The peanut grows flowers above ground, but its “fruit” grows underground. It grows in more countries than most other “nuts”.
The peanut is a native South American plant. Scientists believe that it grew wild in Brazil long ago. They think that for several thousand years the early peoples of South America made it a part of their diet. These peoples were nomads who moved on when a natural food could no longer be found in one area. Along the way they probably let fall some peanuts, which got into the ground and grew. This is believed to be the way the plant reached the place where the Incas（印加人）lived. The Incas, from about 1100 to 1532, thought highly of peanuts. The peanuts were eaten in several forms and used as sacrificial offerings（祭品）to the Incan Sun God. Later in the 16th century, European soldiers had brought peanuts to other parts of the world, including North America, Africa, Asia, Europe, and Pacific Islands.
Although peanuts were found native in South America, they are now grown in almost every country that has warm weather. India produces the most peanuts. China’s production is next, followed by the United States.
The peanut is special in more ways than one. It can be eaten raw, boiled, roasted, or fried. Hundreds of widely different products have been made from it. Carver, an American scientist, set himself the task of discovering new uses for eating and for many other products.
Peanuts are very highly nutritious and are also high in protein （蛋白质）. Americans use about seven-tenths of their protein in the form of meat. In India, where the poor can’t pay for meat or milk, peanut meal and peanut milk have been produced. These have been a great help to the poor.
New products are continually being made from peanuts, among them peanut cheese and a powder that becomes peanut butter when water is added. The fact is that peanuts are so healthy that they were used by astronauts. The unusual nut that isn’t a nut is one of nature’s most amazing gifts.
【小题1】 Although we like eating peanuts, many of us don’t know peanuts belong to _______ family.

London used to be “foggy” for the same reason that cities like Beijing or Chongqing are “foggy” today．The “fog” was in fact smog, a mixture of smoke and fog．In other words, it was made by air pollution．In London, some of this pollution came from factories, but much of it came from the coal(煤)that people burnt in their houses to keep warm during the winter．By the 1950s, London’s smog problem had become so bad that the government decided to do something to clean the air．A new law was made and nobody could burn coal in any British city．Within a few years, the air became much cleaner．There were no more “pea-soupers”．

Many Chinese cities now face the same sort of problem with air pollution that London faced 40 or 50 years ago．However, this problem is more difficult for Chinese cities to solve．One reason is that more of the pollution comes from the factories, rather than from coal burnt in people’s houses．If these factories were closed, this would harm the economy and lots of people would lose their jobs．Another reason is that changing from coal to cleaner fuel(燃料), like gas, is quite expensive．

However, the air in many Chinese cities is becoming cleaner and cleaner, as the government and people pay more and more attention to cutting down pollution．As a result, there are fewer “pea-soupers”in Beijing than there used to be．
